PROMISE TO PAY. BIOMERIDIAN CORPORATION and BIOMERIDIAN INTERNATIONAL, INC.
(referred to in this Note individually and collectively as "Borrower") jointly
and severally promise to pay to ZIONS FIRST NATIONAL BANK ("Lender"), or order,
in lawful money of the United States of America, the principal amount of Two
Hundred Thousand & 00/100 Dollars ($200,000.00) or so much as may be
outstanding, together with interest on the unpaid outstanding principal balance
of each advance. Interest shall be calculated from the date of each advance
until repayment of each advance.

PAYMENT. Borrower will pay this loan on demand, or if no demand is made, in one
payment of all outstanding principal plus all accrued unpaid interest on
December 1, 2001. In addition, Borrower will pay regular monthly payments of
accrued unpaid interest beginning January 1, 2001, and all subsequent interest
payments are due on the same day of each month after that. The annual interest
rate for this Note is computed on a 365/360 basis; that is, by applying the
ratio of the annual interest rate over a year of 360 days, multiplied by the
outstanding principal balance, multiplied by the actual number of days the
principal balance is outstanding. Borrower will pay Lender at Lender's address
shown above or at such other place as Lender may designate in writing. Unless
otherwise agreed or required by applicable law, payments will be applied first
to any unpaid collection costs and any late charges, then to any unpaid
interest, and any remaining amount to principal.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on changes in an index which is the ZIONS

FIRST NATIONAL BANK PRIME RATE (the "Index"). "PRIME RATE" MEANS AN INDEX WHICH
IS DETERMINED DAILY BY THE PUBLISHEC COMMERCIAL LOAN VARIABLE RATE INDEX HELD BY
ANY TWO OF THE FOLLOWING BANKS: CHASE MANHATTAN BANK, WELLS FARGO BANK N.A., AND
BANK OF AMERICA, N.A. IN THE EVENT NO TWO OF THE ABOVE BANKS HAVE THE SAME
PUBLISHED RATE, THE BANK HAVING THE MEDIAN RATE WILL ESTABLISH LENDERS' PRIME
RATE. IF, FOR ANY REASON BEYOND THE CONTROL OF LENDER, ANY OF THE AFOREMENTIONED
BANKS BECOMES UNACCEPTABLE AS A REFERENCE FOR THE PURPOSE OF DETERMINING THE
PRIME RATE USEII HEREIN, LENDER MAY, FIVE DAYS AFTER POSTING NOTICE IN LENDERS
OFFICES, SUBSTITUTE ANOTHER COMPARABLE BANK FOR THE ON[ DETERMINED UNACCEPTABLE.
AS USED IN THIS PARAGRAPH, "COMPARABLE BANK' SHALL MEAN ONE OF THE TEN LARGEST
COMMERCIAI BANKS HEADQUARTERED IN THE UNITED STATES OF AMERICA. THIS DEFINITION
OF PRIME RATE IS TO BE STRICTLY INTERPRETED AND I~ NOT INTENDED TO SERVE ANY
PURPOSE OTHER THAN PROVIDING AN INDEX TO DETERMINE THE VARIABLE INTEREST RATE
USED HERE11, IT IS NOT THE LOWEST RATE AT WHICH LENDER MAY MAKE LOANS TO ANY OF
ITS CUSTOMERS, EITHER NOW OR IN THE FUTURE.. Lender will tell Borrower the
current Index rate upon Borrower's request. Borrower understands that Lender may
make loans based on other rates as well.

The interest rate change will not occur more often than each DAY. The Index
currently is 9.500% per annum. The interest rate to be applied to the unpaid
principal balance of this Note will be at a rate of 0.500 percentage points over
the Index, resulting in an initial rate of 10.000% per annum. NOTICE: Under no
circumstances will the interest rate on this Note be more than the maximum rate
allowed by applicable law.

penalty all or a portion of the amount owed earlier than it is due. Early
